The Assassina SPT-8098. Perfect for killing without a trace. Just slap a plastic bag over it to contain the GSR, load it with subsonic frangible .22s, blow away the target with a headshot at close range, wrap the barrel and any remaining cartridges in the bag, and toss it in a remote river. Subsonic rounds and a Nagant action allow a totally silent weapon, and cartridges can be made by pushing the bullet of a downloaded .22 WMR down until it is completely covered by the case. Frangible rounds mean that even if they find your barrel, they shouldn't be able to match the bullets to it, and the whole thing is made mostly of titanium (for weight) and can fit in your pocket. Developed by the Cordian Department of Foreign Affairs, Games and Theory (read; espionage) Bureau for use by Agents in sensitive assassination cases. Has no serial number, and technically never existed. Go ahead, ask the government. They'll deny ever hearing of such a weapon. Ugly as sin it might be, but damn if it isn't effective.
